Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.B-tier. Still early. Manus is more flexible for less money.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
